  • Patent number: 10374859
    Abstract: The present disclosure relates to a 5G or pre-5G communication system for providing a higher data rate after a 4G communication system such as LTE. Particularly, the present disclosure relates to pre-processing for Filter Bank Multi-Carrier (FBMC) in a wireless communication system, and a method of a communication node includes the operations of receiving a signal from a counterpart node, determining a pre-processing scheme according to a channel and a frequency confinement characteristic of a filter based on the received signal, and performing pre-processing for a subcarrier set corresponding to the filter in accordance with the determined pre-processing scheme.

  • Patent number: 10051631
    Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). An operation method of an apparatus may include generating an initial detection result based on signals received through a plurality of carriers from a transmission device; determining a first detection area in the initial detection result based on a channel gain; generating a plurality of first symbol groups by inserting available symbols into the first detection area of the initial detection result; and generating a first detection result based on a first symbol group with the maximum likelihood among the plurality of first symbol groups.

  • Patent number: 9654312
    Abstract: The present invention relates to a frequency region equalization method and an apparatus therefor in a cellular environment on the basis of a QAM-FBMC system. A method for receiving a signal by a receiver according to one embodiment of the present invention may include: performing channel estimation; comparing a minimum channel gain with a predetermined first threshold value; and performing layered detection when the minimum channel gain is smaller than the first threshold value. According to one embodiment of the present invention, a gain can be acquired in terms of a BER even while a structure of a symbol level equalizer is maintained.
